In anticipation of a devoted observing campaign, we have performed some
quick exploratory observations of three of the acc-SySt discovered in
this paper with the Swift satellite [1]}, and
for comparison of three of the identified radial pulsators considered as a
control sample. The observations have been carried out in
Target-of-Opportunity mode. This type of observations is generally limited
to roughly 2000 seconds per object, so this can be considered as a quick and
rather shallow survey of our target sample. The pointings were performed in
two time slots: the first one in September-October 2019, and the second one
in June 2020. The results are summarized in Table REF .
